"Other people dont need commercial mocks at all and do just fine with the free ones. I would say the biggest advantages to JQ+ and to many other commercial mocks is the number of questions (generally several hundred), the customizability, and the environment that simulates the real test."
I am one of there peopel. Since you are asking
if what you have is enough i would say yes. I am
not saying JQ+ is not good.
Some of the free mock exams are really good. They don't have a nice UI but authors spent a lot of time on them. The questions are close to the real exam and clear. I found them very use like the
RHE sample exams that came with the book.
Just thought u might want to hear from both side.
Good luck on your exam!
